HFT High Frequency Transducer

Everyone's on a budget. Given enough time and effort most of us eventually realize the biggest bang for the buck is a holistic approach that includes tweaks like HFTs and cones and interconnects and power cords right up there with the more traditionally recognized components like amps and speakers. 

The thing of it is, there are now so many different products capable of producing so much improvement so cost-effectively that the greatest challenge today is to develop the listening skills and evaluation experience to be able to make effective choices. I mean, look: BDR Cones, SR HFT and Blue Quantum Fuse are all incredible values for the improvement in SQ they deliver. But the only way of proving that, and the only way of knowing which is best for your system in its present state is to, as folkfreak said, give it a try.

Just be sure to follow Audiophile Rule Number One: Never buy anything you haven't first auditioned, unless it can be returned no questions asked.

btw oops my bad, I got the special above wrong. Its buy 2 get 1 free.

The most cost effective then would probably be something like buy one HFT pack of 10, and one Speaker Kit, and get one HFT Wide Angle Kit free.
The speaker kits are one kit or 6 per speaker, but I know from experimenting you can get really good results with half that, or 3 per speaker. Actually these things are so effective even just one or two is amazing and really makes the speakers disappear. Guess I will find out next week what a full kit treatment will do!

I just wanted to post on this old thread the wonderful results I've obtained placing one HFT in the center of each of the four 7.5ft tall x3.5 ft wide glass windows that align side-by-side and make up much of the left wall of my listening room. Completely eliminated the glare.  I use them in conjunction with standard placement of 10 other HFTs in the room and HFT 2.0's on my speakers.  I also have traditional GIK and ASC absorption and diffusion in the room, however the glare remained until I added the HFT's to the windows.  Tamed the glass resonance perfectly while enhancing the overall imaging and soundstage IMO.

Wait a few days. The glare will be back.

Ok, I'm one of the biggest skeptics when it comes to a lot of tweaks.  When I was at RMAF last year and visited the Synergistic Research room, they did a real time demonstration of the effect of the HFTs.  The room was treated with them and when they removed just a few of them and played the same track the sound stage collapsed and the definition of the instruments was more diffused.  Yes they are expensive for a handful of "audio buttons" but they made a noticeable positive improvement in my system.  The best advise I can give you is try them out for yourself if you can get a guaranteed return policy.  I would recommend 10 to 15 or they have specials from time to time.
